Title: Method of screening groups of radioactive molecules and applications thereof
Inventor: DIVE VINCENT
IPC: A61K38/00
Filed: 2003-05-28
Abstract: The invention relates to an amplification-free method of screening groups of radioactive molecules, the products from the molecule groups obtained and the application thereof in order to identify molecules that are capable of binding selectively to a tissue or a particular organ. The inventive method can be used for the development of novel therapeutic compounds and contrast agents for medical imaging and for the screening of medicaments. Said method of screening a group of molecules is characterised in that it comprises at least the following steps: (1) the group of molecules is administered to at least one animal, each molecule being marked first by a suitable radioactive isotope; (2) at least one of the animals is slaughtered and the tissue distribution of the radioactivity of the molecules administered is analysed from sections of tissue or organs taken using suitable imaging devices; (3) sections of tissue or organs in which a radioactivity signal is detected are selected; (4) radioactive fractions from the aforementioned sections of tissue or organs selected during step 3 are isolated using suitable techniques such as chromatography and/or extraction techniques; and (5) the molecule(s) from the radioactive fractions obtained in step 4 are characterised using suitable analysis techniques such as chromatography and/or mass spectrometry. According to one variation of the method, in step 2, where possible, the tissue distribution of the radioactivity of the molecules administered is analysed in vivo using suitable imaging devices from a biological sample which is pre-extracted and selected from the group containing cells and sections of tissue or organs. As a result, said variation does not require the animal to be slaughtered.

Title: Highly bandwidth-efficient communications
Inventor: NAISH ROBERT R
IPC: H04B1/7107
Filed: 1998-02-24
Abstract: A discret multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT).  This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment. Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms. In a specific embodiment the spectral and spatial components of the adaptive weights are calculated in a unified operation based on the mathematical analogy between the spectral and spatial descriptions of the airlink.

Abstract: A device and method for deagglomerating powder agglomerates for inhalation.  The device includes an inlet (20) connected to a chamber (40) and to a powder source for supplying the chamber with powder agglomerates and a flow of gas that define a swirling fluid flow inside the chamber. The device also includes an outlet (22) connected to the chamber for inhalation such that the swirling fluid flow in the chamber can exit from the chamber as a longitudinal fluid flow that is directed along a longitudinal axis (X) of the outlet, and a secondary fluid flow that is directed away from the longitudinal axis of the outlet. A mesh (28) in the outlet prevents powder agglomerates above a predetermined size from traversing the mesh, and reduces the secondary fluid flow relative to the longitudinal fluid flow exiting from the chamber to thereby reduce powder deposition in a mouth and throat of a user.

Abstract: The present invention relates to methods and system for the diagnosis diseas es or conditions. In a particular aspect, a disclosed method for determining a panel includes calculating a panel response for each patient in a set of diseased patients and in a set of non-diseased patients. The panel response is a function of the value of each of a plurality of markers in a panel of markers. The method also includes calculating a value for an objective function. The objective function is indicative of the effectiveness of the panel. The steps of calculating a panel response for each patient and calculating a value for an objective function are iterated by varying at lea st one of the parameters relating to the panel response function and a sense of each marker to facilitate optimization of the objective function. The objective function may be a measure of an overlap of panel responses of diseased patients and panel responses of non-diseased patients. The contribution of each marker to the objective function may be determined, and the panel size may be reduced by removing the poorest markers. Thus, an optimum panel of markers and an optimal panel response function for the diagnosis of a disease or condition may be determined.

Abstract: Method and device for the detection of Co in a hydrogen-rich gas stream. Such a gas stream is, for example, fed to a fuel cell. Detection takes place with the aid of a miniature electrochemical cell and is based on the principle that carbon monoxide that moves past the anode screens the anode material, as a result of which the reaction with hydrogen at the anode is impeded. By determining the decrease in the current density it is possible to determine the degree of screening as a function of time and thus the percentage CO.  According to the invention the gas is fed past the anode only and the cathode is in direct contact with a water bath.

Title: Systems and methods for optical media modification
Inventor: HOWARD DANIEL G
IPC: G11B20/00
Filed: 2004-02-05
Abstract: Theft, distribution, and piracy of digital content on optical media (software, video, audio, e-books, any content of any kind that is digitally stored and distributed) is often accomplished by copying it directly to another disc using commonly available copy tools and recordable optical media, or the copying of media to another mass manufactured disc. Methods which cause the copy process to become lengthy and inconvenient, or which produce copies that are significantly measurably different from the original and therefore be recognizable as copies, may deter or prevent an unauthorized individual from making copies. In addition, methods which generate an intended slow-down in the read process of the media can be used to authenticate the media at run time. This offers significant advantages to content creators who wish to protect their products.
